在PySide2中使用自定义图像提供程序处理16位灰度图像

from PySide2.QtGui import QImage, QPixmap
from PySide2.QtCore import QAbstractListModel, QModelIndex, Qt

class CustomImageProvider(QAbstractListModel):
    def __init__(self, images, parent=None):
        super().__init__(parent)
        self._images = images

    def rowCount(self, parent=QModelIndex()):
        return len(self._images)

    def data(self, index, role=Qt.DisplayRole):
        if not index.isValid() or role != Qt.DisplayRole:
            return None
        image_path = self._images[index.row()]
        # Load 16-bit grayscale image
        qimage = QImage(image_path, "TIFF")  # Assuming TIFF format for 16-bit grayscale
        if qimage.isNull():
            return None
        # Convert QImage to QPixmap for display
        pixmap = QPixmap.fromImage(qimage)
        return pixmap

from PySide2.QtWidgets import QApplication, QListView

app = QApplication([])
image_paths = ["path/to/image1.tiff", "path/to/image2.tiff"]  # List of 16-bit grayscale image paths
model = CustomImageProvider(image_paths)
view = QListView()
view.setModel(model)
view.show()
app.exec_()
